I didn't down-vote you, because you ask a valid question.

However, free newspapers and travel sounds good to me.

If all/most resources were free it would then be just a matter of deciding which were worth spending your time on.

There doesn't really seem to be much negative, other than current business models fading away. However, I don't think most people would care much if all businesses did close and were replaced with a different economic model. (Not that I have one in mind, just that I don't think we need to be attached to the current business model)

The EU provides a lot of funding for science projects across the union, this funding comes from member states, who raise money through taxation.

So in effect you have EU citizens paying for research to be done, but have to double-dip on the papers or artefacts that come out as a result of the research.

This initiative is designed to make publicly funded research.....public, and not held behind a paywall provided by a private entity.
